In a large skillet, sauté sausages with bell pepper, onion and olive oil - cooking until sausage is lightly browned and about half way done. Add half of the marinara sauce, stir to blend and remove to a casserole pan.

Nestle stuffed shells into sausage and peppers, drizzle with remaining marinara sauce and top with cheese. Roast in preheated oven until bubbling and lightly browned, about 15-20 minutes. Serves about 4.---
